If not fixed the rattling kills the rings and the motor uses more oils than petrol. I had my motor rebuilt at only 11000K on the clock with the latest revision pistons to stop this problem, Heaps that are buying the GEN 111 second hand don't know this and they are being sucked in because they never asked to be there to start the engine COLD The Car Yards are smart they start them up before you get there or they start them in the morning to remove the slap when cold , it takes up to 8 hrs to get the engine cold enough to test it if its rattles, Trust me I'm an expert on this matterI have close family members that work for Holden in Melbourne and I was concerned once I read below and mine failed the test. By the way around 22% of all the Gen111 from VX to late VY all fail the test and HAVE to be rebuilt.<br />Read this forum they even ran a poll on all owners of Gen111 Australia wide. Just to let you know, every Gen111 engine ever built and fitted to any VX series on any model or any VY on any model all suffer from this problem and all should have been recalled, but that would have cost super millions. Holden had a policy, only rebuild if you super complain, as all the above fail in the long run. They have had 4 revisions of pistons to fix this problem and only revision 3 and 4 have solved the problem. Revision 1 and 2 had to come in again to be replaced. Revision 4 pistons have correct tolerance pistons, revised gudgeon pin clearance, revised gudgeon pin oiling, revised oil groove clearance, location of top piston ring, different types of rings and the pistons are teflon coated. This alone only solves the problem.<br />Trust me even my 9 year old boy knows this problem ( he has heard it enought from mine or others) and I has tested a few of others to give them the good or bad news.<br /> http://www.ls1.com.au/forum/forumdisplay.php?f=31 <br /> <br />Remember look for the SEARCH option and Type Piston Slap.<br />Also read<br /><br /> <br /> <small>[ 16.
